In the 1960s, an important geocentric experiment was triggered: 50 years ago, the Soviet Union planned to dig through the earth, but why did it choose to give up when it dug to the depth of1.20,000 meters? What the hell is going on?
With the end of World War II, the United States and the Soviet Union also launched a fierce competition for hegemony. In 60 years, American scientists first put forward the geocentric drilling plan, and started construction near the coast of La Jolla in 196 1 year, drilling 3 15 meters under the seabed with a depth of 948 meters.
Due to the technical difficulty and high cost of this project, the US Congress finally stopped funding, and drilling could only come to an end. However, this aroused the interest of the Soviet Union, and they also decided to take a "trip across the earth".
After intensive preparations, Soviet scientists gave up submarine work closer to the center of the earth and chose kola peninsula, which is extremely cold in the north. The Soviet side has also assembled huge manpower and material resources.
Under the leadership of the Minister of Geology of the Soviet Union, this activity was finally implemented on May 24th, the anniversary of Lenin's birthday100th.
All the people involved in this project got an apartment from Moscow, and the per capita monthly salary is comparable to the annual salary of a university professor, which shows that high-level officials attach importance to this experiment.
The principle of the drilling rig is also very simple, that is, the rotating drilling rig is installed on a drill pipe, and the cooling liquid is continuously injected while rotating to make it stable. When one drill bit fails, the staff will replace it with another.
By the end of 1983, this ultra-deep drilling in Konkola had advanced by12000m. But from 183 to 1993, it is less than 262 meters. Why? It was not until 1949 that the reason for stopping the project was understood as that the federal government further decrypted the information at that time.
It turns out that the whole project still encounters the problem of overheating, which is affected by the internal temperature of the earth. On average, for every drop of 100 meter, the formation temperature will increase by about 4 degrees. At the depth of 10,000 meters, it is already a high temperature of several hundred degrees. According to the researcher's description, even a solid drill bit will be "as soft as noodles" in this case, and its efficiency and durability will be greatly improved. It is very difficult to move forward.
At the same time, the Soviet Union itself encountered various crises. In the 1980s, it was mired in the war in Afghanistan, and the funds available for ultra-deep drilling in Kola became more and more limited.
1993, the Russian government, which succeeded the Soviet Union, finally officially announced that it had stopped drilling experiments due to lack of funds. After that, the research institute near the ultra-deep borehole in Kola has been running for more than ten years, checking the substances brought by the deep surface. It was not until 2008 that drilling was officially abandoned.
Although it failed to reach the goal of getting through the earth, the depth of 1.2 million meters, or even the radius of 6300 kilometers on the earth's surface, it still made contributions to the times. Its drilling depth kept a record for decades, and it was not broken until 2008 by an oil rig in Qatar. I hope people can make greater scientific and technological achievements in the future.
